A health food store sells oatmeal for $3.60 per pound and bran flakes for $4.80 per pound. How many pounds of each should be used to get a mixture of 30 pounds that sells for $4.00 a pound?
\n" ); document.write( "
\r\n" );
document.write( "First you have the AMOUNT OF CEREAL equation:\r\n" );
document.write( "\r\n" );
document.write( "\"%28matrix%285%2C1%2C%0D%0ANumber%2C%0D%0Aof%2C+%0D%0Apounds%2C%0D%0Aof%2C%0D%0Aoatmeal%29%29\"+= or x + y = 30  \r\n" );
document.write( "\r\n" );
document.write( "And second, you have the AMOUNT OF MONEY equation:\r\n" );
document.write( "\r\n" );
document.write( "+= or (x)(3.60) + (y)(4.80) = (30)(4.00) or 3.6x + 4.8y = 120\r\n" );
document.write( "\r\n" );
document.write( "So you have this system of equations:\r\n" );
document.write( "\r\n" );
document.write( "x + y = 30\r\n" );
document.write( "3.6x + 4.8y = 120 \r\n" );
document.write( "\r\n" );
document.write( "Solve that system and get x = 20 and y = 10.\r\n" );

document.write( "Answer: 20 pounds of oatmeal and 10 pounds of bran flakes. \r\n" );
